especialy seeing that the Chayei Adom (127:3) cautioned against using snuff tobacco that was known to contain yayin nesech as an additive and The Magen Avrohom in Hilchos Pesach (467:8:10) prohibited using tobacco during Pesach, which was known to have been soaked in beer beforehand.

According to the cRc they probably do. However I disagree. Se what I have written here. The same argument applies here as well, except with an added leniency: You don't know whether there is non-kosher stuff inside there, and even if there is, it is mixed into the tobacco and unrecognizable. Thus it could be said that even the Rema would agree to be lenient here l'chatchila. For further elaboration, see what I have written in this blog post.

Dov you say that as a general rule that any foodstuffs read the ingredients and then if nothing is not kosher than you can eat it?

Correct, that is Rabbi Abadi's position. However what I was writing here does not need to come on to that. If you have personal questions I would rather you direct them to my email address or my blog; feel free to do so.
